T5.2.6 mixins example
Hi,
i search an example how to create and use mixins.
Unfortunately, i cannot found anything to become smarter.
My idea - i write a mixin which set TextField disabled or not depends on
logged user.
My example code
class FieldMixin{
@Inject
private ComponentResources resources;
private Element element;
@SessionState(create = false)
private WebUser user;
void beginRender(MarkupWriter writer){
element = writer.getElement();
if(user.getName().equels("admin"){
element.attribute("disabled", "disabled");
}
}
}
TML
...
<t:textfield t:id="fieldA" t:mixin="FieldMixin" />
...
Is this the right way?
How can i get it running?
greeting,
resign

I have just tested. You should add the @MixinAfter annotation to your Mixin
class.

I think, setting the disabled property in the beginRender phase is to
early, because the textfield is not rendered yet. So the current element is
th <td>.
Do it in the afterRender phase.

Does the disabled attribute alread exist in your template.
If it is, according to the JavaDoc, the attribute method will not work. Try
with the forceAttributes method.
Can you also check if your SessionsState-annotated variable is correct, and
also the current element.

The right syntax is :
<t:textfield t:id="fieldA" t:mixins="FieldMixin" />
